1. Polyester, commonly known as polyester, is a type of synthetic fiber. It is produced by the condensation polymerization of organic dicarboxylic acids and diols, resulting in synthetic polyester fibers through spinning. This fiber is also referred to as PET fiber and is a type of...
2. Polyester fiber fabrics are made from polyesters synthesized by the condensation of organic dicarboxylic acids and diols. Reportedly, industrial production of polyester fibers uses polyethylene terephthalate, which is referred to as polyester in China. This synthetic fiber is the largest ...

5.This "green" technology, Petretec(sm), recycles all forms ofpolyester, "unzipping" it into monomers suitable for repolymerization or other uses. 这项绿色技术可以回收各种酯,将其断裂为单体以便再合或其它用途。 6.Thepolyesteror copolyester can be converted into dimethyl terephthalate of binary acid...
Crimping: When the fiber is drawn out it is long and smooth. Crimping can give the fiber more texture and bulk and can increase its insulation properties, as well as its elasticity Making Yarns After the fiber itself is created, it is made into a yarn. There are two types of polyester ...
10. Natural fibers, including cotton, linen, silk, and wool, are derived from plants and animals. They are categorized into woven, knitted, and nonwoven fabrics, each with its own uses and characteristics.11. Knitted fabrics, created by interlooping yarns, are commonly found in T...
Particle sizes <100 m gave similar compression properties and cell size to virgin foam at up to 10 parts by weight on 100 parts of polyol, but cell structure and compressive properties showed increasing divergence as particle size and addition concentration increased. Studies of alternative uses ...
